Lightweight Intrusion Detection System for Secure Data Transmission in Switched Network Environments

While increased internet connectivity offers numerous benefits, it also raises the risk of cyber-attacks by creating more points of vulnerability through system-to-system, system-to-server, and system-to-internet interactions. These interactions can be exploited to gain control over systems and their connected devices. Although security vulnerabilities and mitigation strategies have been extensively studied, there remains a significant gap in understanding how cyber-attacks leverage these vulnerabilities to compromise system performance and operations. In the context, we propose a Lightweight Intrusion Detection System (LIDS) for Secure Data Transmission in Switched Network Environments. The proposed system ensures the authenticity of data packets and prevents unauthorized nodes from joining the switched network. Specifically, the LIDS is capable of detecting both unauthorized and compromised nodes in the Switched Network Environments. The proposed LIDS is simulated extensively, and its performance is compared with state-of-the-art approaches. The results demonstrate that LIDS outperforms existing approaches based on the performance metrics evaluated in the simulation, and achieves a detection rate 5% greater than that of the existing approach.
